There has been a lot of buzz floating around about Facebook's new search being launched called Facebook Graph. This will be using algorithms based on what is in Facebook, not the usual web page based content we are all used too.  I guess you could call this more of a Social Media Engine rather than a Search Engine.

I have also seen much talk about new ways for people to play dirty with this, just as the blackhat's used to do before Panda. I'm sure many businesses will get spammed about services promising followers and likes (I hate people who offer this on Twitter), and some bad players will run off with unsuspecting money for the people who will fall for this.
